Study Notes
Introduction
- Abnormal bleeding can be caused by disorders in the vascular system, platelets, or coagulation factors.
- Vascular disorders can lead to bleeding from mucous membranes and into the skin.
- Platelet disorders can lead to bleeding from mucous membranes and into the skin.
- Coagulation factor disorders can lead to bleeding into joints or soft tissues
Types of Hemorrhage
- Petechiae are very small, pinpoint bleeding spots.
- Purpura are slightly larger bleeding spots.
- Ecchymoses are larger areas of bleeding, also known as bruises.
- Hematomas are large collections of blood that pool in tissues.
Vascular Disorders
-
Hereditary Hemorrhagic Telangiectasia is an inherited disorder with dilated capillaries that lead to bleeding.
- Telangiectasia may be pinpoint, nodular, or spiderlike in appearance.
- This disorder appears in childhood and becomes more numerous in adulthood.
-
Connective Tissue Disorders are characterized by fragile vascular systems.
- Senile Purpura: This occurs in older age groups due to a decrease in collagen and elastin.
- Scurvy: Caused by vitamin C deficiency, leading to weak blood vessels and bleeding gums.
- Steroid Purpura: Common side effect of steroid therapy.
- Giant Hemangioma: Caused by an abnormal growth of blood vessels.
Hereditary Hemorrhagic Telangiectasia
- An uncommon, autosomal dominant disorder.
- Abnormal blood vessels (Telangiectasia) can appear in the skin and mucous membranes.
Ehlers Danlos Syndrome
- A rare connective tissue disorder with abnormal collagen formation.
- Characterized by:
- Extreme vascular fragility
- Skin hyper-elasticity
- Hyper-extensible joints
Marfan's Syndrome
- An inherited, autosomal dominant disorder associated with abnormal collagen formation.
- Characterized by:
- Skeletal defect (long extremities)
- Ocular defects
- Cardiovascular defects
Osteogenesis Imperfecta
- An autosomal dominant disorder.
- It is a collagen vascular disorder, leading to brittle bones.
- Causes a lack of bone matrix.
- Can be a fatal disease, and those with the condition often die early.
- Leads to a poor quality of life.
